However, when the tension plate 52R is provided on the front side of the alignment device 54R on the outside of the machine body, the alignment on the inside of the machine body is performed. When the tension plate 52L of the device 54L is provided on the rear side of the machine body with respect to the tension plate 52R of the alignment device 54R, the tension plate 52L or the tension plate when the large diameter foliage passes between the left and right of the alignment devices 54L and 54R. Since the alignment chain 48 and the alignment guide body 52 move to the side without the 52R, even if the diameter of the carrot foliage is large, it can be prevented from being bitten by the alignment devices 54L and 54R, and the aircraft is stopped. It is not necessary to remove the bitten foliage and work efficiency is improved.

  In addition, if the tension of the tension plates 53L, 53R is set to be weaker than the tension of the tension springs 50, 50, the alignment chains 48, 48 will be in an appropriate position when the large-diameter foliage passes and a load is applied. Can be bent and retracted, and can be prevented from being bitten by 54L and 54R, and it is not necessary to stop the body and remove the bitten foliage, thereby improving work efficiency.

  Then, elongated holes are formed in the transmission cases 37, 37 in the vicinity of the alignment drive sprockets 42, 42 and outside the alignment guide bodies 52, 52, and the surfaces of the alignment guide bodies 52, 52 are formed in the elongated holes. The left and right scrapers 55 and 55 for removing pieces and mud of the foliage adhering to the head are attached along the locus of the alignment guide bodies 52 and 52 at the time of position adjustment.

In addition, the scrapers 55 and 55 are arranged in a rearward downward inclined posture, so that it becomes easy to drop the cut ends of the foliage and mud downward.
Then, left and right cutting blade rotation shafts 56 and 56 are attached to the rear positions of the alignment devices 54L and 54R of the left and right first gear units 38 and 38, and left and right bearings 57 and 56 are mounted on the cutting blade rotation shafts 56 and 56, respectively. 57 is attached rotatably. Then, left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and left and right foliage cutting blades 60, 60 are attached to the support plates 59, 59 to constitute a foliage cutting device 61.

  Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right foliage conveyance drive pulleys 62 and 62 are attached to the front side of the machine body above the left and right first gear units 38 and 38 and above the alignment devices 54L and 54R. The foliage driven pulleys 63 and 63 are rotatably attached. Then, the left and right foliage conveying belts 64, 64 are wound around the left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 to endlessly form the carrot foliage from the pulling and conveying device 24. Is disposed below the left and right transmission cases 37 and 37 and below the end of conveyance of the pulling and conveying device 24.

  Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

A foliage shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the end portions of the above-mentioned foliage conveyance device 65 and the remaining leaf conveyance device 70 to the field is provided to constitute the foliage cutting portion D.
With the above configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions separated from the left and right spacing portions of the alignment devices 54L and 54R through which the foliage passes, so that the alignment drive sprockets 42 and 42 Since it is possible to prevent the stems and leaves from being entangled with the two output shafts 41 and 41 to stop the alignment devices 54L and 54R, the harvesting operation is not interrupted and the work efficiency is improved.

  In addition, since the alignment drive sprockets 42, 42 have a smaller diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42 are further left and right of the alignment devices 54L, 54R. Since it leaves | separates from a space | interval part, it can further prevent that a foliage part gets entangled with the alignment drive sprockets 42 and 42 and the 2nd output shafts 41 and 41, and working efficiency further improves.

  The left and right tension springs 50 and 50 for tensioning the alignment driven sprockets 45 and 45 are provided, so that the left and right alignment chains 48 and 48 are generated when the foliage comes into contact with the alignment devices 54L and 54R. Since the slack can be absorbed and the alignment chains 48 and 48 immediately return to the tensioned state, the alignment devices 54L and 54R ensure that the ginseng foliage even when the foliage portions having different diameters pass continuously. The cutting position of the carrot foliage is properly aligned and the foliage is cut appropriately, and there is no need to remove the foliage in a later process, improving the work efficiency.

  Further, the tension of the tension springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the growth status of the carrots, the difference in the diameter of the foliage depending on the variety, or the weather and soil quality The tension can be changed appropriately according to the working conditions at the work place, etc., so that the stems and leaves remaining in the carrots are removed in the subsequent process by properly aligning the carrot foliage cutting position and cutting the foliage parts reliably. This eliminates the need for work efficiency.

  Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 tensioned by the tension springs 50, 50 move toward the conveyance path of the foliage portion, so that the small diameter foliage portion passes through. Thus, the alignment devices 54L and 54R can receive the foliage portion to properly align the cutting position of the ginseng foliage portion, eliminating the need to remove the foliage portion remaining in the ginseng in a later process, and improving the work efficiency.

  Further, when a large load is applied to the left and right alignment devices 54L and 54R when the large diameter foliage part passes, the alignment driven sprockets 45 and 45 are separated from the movement path of the foliage part along the holes 44 and 44. Since the left and right intervals on the front side of the alignment devices 54L and 54R are widened, the foliage can be prevented from being caught in the interval portions of the alignment devices 54L and 54R, and the aircraft is stopped and bitten. There is no need to remove the foliage and the work efficiency is improved.

  If it is known before harvesting that the carrot foliage has a large diameter, move the alignment driven sprockets 45, 45 away from the left and right of the left and right alignment devices 54L, 54R. If the left and right distances on the upper side in the conveying direction of the alignment devices 54L and 54R are widened, the alignment devices 54L and 54R can be prevented from biting the foliage, and it is necessary to remove the bitten foliage. No work efficiency is improved.

  And, by attaching the guide cover 51 to each of the plurality of links 48a constituting the alignment chains 48, 48 and configuring the alignment guide body 52, the guide cover 51 at an arbitrary location can be freely attached and detached. Even if some of the guide covers 51 are damaged, the proper alignment performance is maintained by simply replacing the guide covers 51 with new ones, and the foliage is appropriately cut, so that the work efficiency is improved.

Moreover, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.
Furthermore, since the guide cover 51 can be attached and detached manually without the need for a tool, the replacement work can be easily performed.

  Since the guide cover 51 has a U-shape in front view covering the contact surfaces of the upper and lower surfaces of the alignment chain 48 and the foliage, a space portion is generated between the guide cover 51 and the alignment chain 48. As a result, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that ginseng is not aligned at the proper cutting position and the foliage is left uncut, and the foliage is removed in a later process. The work efficiency is improved, the carrot root is prevented from being cut, and the product value of the carrot is improved.

  Further, a convex R portion 51 a and a concave R portion 51 b are formed on the guide cover 51, and the convex R portion 51 a of the subsequent guide cover 51 is brought close to the concave R portion 51 b of the front guide cover 51. By attaching to the alignment chain 48, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide cover 51 can move following, so that the alignment devices 54L and 54R Since it operates at a constant peripheral speed, it is possible to properly align the cutting positions of the carrot foliage by receiving the foliage, eliminating the need for removing the foliage remaining in the carrot in a later step, and improving the work efficiency.

  Furthermore, by providing a protruding portion 51c that protrudes toward the convex R portion 51a, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide covers 51 ... Since this protrusion 51c covers the space formed between the front and rear, the foliage is sandwiched between the space between the front and back of the guide covers 51, so that the ginseng is not aligned at an appropriate cutting position and the foliage is left uncut. This eliminates the need to remove the foliage in the subsequent process, improves the work efficiency, prevents the carrot root from being cut, and improves the product value of the carrot.

  When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. Since the alignment chains 48 and 48 of the portion where the tension plate 53L or the tension plate 53R is not pressed can be retracted in the direction of the alignment drive sprockets 42 and 42, the foliage is bitten between the right and left of the alignment devices 54L and 54R. There is no need to remove the foliage that has been bitten by stopping the airframe, and the work efficiency is improved.

  Further, by providing left and right scrapers 55 and 55 for scrubbing debris and dirt such as mud adhering to the alignment guide bodies 52 and 52 moving on the outer periphery of the alignment drive sprockets 42 and 42, Since it is possible to remove the foreign matter adhering to the alignment guide bodies 52 and 52 at a position away from the moving path of the parts, the foliage fragments are prevented from getting entangled with each part of the alignment devices 54L and 54R. It is not necessary to remove the entangled stem and leaf fragments, and the work efficiency is improved, and the mud mass is prevented from damaging the root of the carrot, thereby improving the product value of the carrot.

  Furthermore, since the attachment positions of the scrapers 55 and 55 can be changed along the elongated holes, the scrapers 55 and 55 are set at optimum positions in accordance with the average diameter of the ginseng stalks and leaves of the field where the harvesting operation is performed. The above-described effect is further improved by reliably removing the debris of the foliage and dirt such as mud from the alignment guide bodies 52 and 52.

  And the leaf shooter 71 which discharges the leaf leaves cut from the carrot by the stem-and-leaf cutting device 61 (the cut stem and leaf portion) to the field seems to discharge the leaves and leaves to the already dug side (the side where the carrot has been harvested). Are provided in a downwardly inclined posture, the discharged stems and leaves fall on the carrots on the undigged side (the side on which the carrots are not harvested), and the drainage leaves the left and right nipping and conveying belts 18 and 18 and the left and right driven Since it is possible to prevent the harvesting part C from being entangled with the pulleys 16 and 16 and hindering the harvesting operation, the work efficiency is improved, and the fallen leaves that fall on the carrots hinder the visibility of the carrots to be harvested. Can be prevented.

(Remaining leaf processing part)
Next, the remaining leaf processing unit E will be described.
As shown in FIGS. 1 and 7, front and rear remaining leaf processing frames 72 and 72 are provided below the foliage cutting device 61, and the first remaining leaves are disposed between the left and right sides of the left and right sides of the body of the remaining leaf processing frames 72 and 72. A processing roller 73a is rotatably attached. A second remaining leaf processing roller 73b is rotatably mounted between the left and right sides of the left and right sides of the remaining leaf processing frames 72, 72 and below the first remaining leaf processing roller 73a. Then, a remaining leaf processing belt 74 made of an elastic material such as rubber or urethane is wound around the first remaining leaf processing roller 73a and the second remaining leaf processing roller 73b in an endless manner. Further, a remaining leaf processing roller 75 is attached to the upper portion of the remaining leaf processing belt 74 so that the remaining leaves remaining at the root of the carrot are sandwiched together with the remaining leaf processing belt 74 and rotated to be excised. The remaining leaf processing section E is configured by configuring the remaining leaf processing conveyor 76 that transports the remaining leaves from the outside of the machine body to the left and right inside directions while processing the remaining leaves.

The remaining leaf processing conveyor 76 is inclined about 2 to 5 degrees from the left and right sides of the machine body to the other side.
Thereby, since the carrot which fell is moved by the drive and inclination movement of the remaining leaf processing belt 74, the movement of the carrot does not stop on the remaining leaf processing conveyor 76, and it is necessary to move the carrot stopped manually. No work efficiency is improved. Further, since the residual leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the residual leaf processing conveyor 76 is inclined with respect to the ground even if the aircraft is inclined to the left and right sides depending on the state of the field. Since the carrot remains in a substantially horizontal state, the carrot does not stagnate on the remaining leaf processing conveyor 76 and does not move in the direction opposite to the conveying direction of the remaining leaf processing conveyor 76. There is no need to return it and work efficiency is improved.

  With the above configuration, since the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 cuts off the remaining leaves of carrots cut by the stem and leaf cutting device 61, the operation of manually cutting the remaining leaves after the harvesting operation is omitted. Work efficiency can be improved.

  In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.

The hanger arms 95, 95 are configured to be movable upward or downward only when a moving force greater than the resistance force is applied upward or downward due to the frictional resistance of the frictional resistors 94, 94 sandwiched therebetween.

  A hanger frame 96 that protrudes in the front-rear direction from the front-rear end of the body of the sorting and conveying conveyor 87 is attached to the ends of the hanger arms 95, 95 in the front-rear direction. A pair of front and rear hanging hangers 98 and 98 for hanging and supporting a storage bag (flexible container bag) 97 for holding the front and rear and left and right are attached to the storage bag (flexible container bag) 97 so as to be rotatable in the left and right direction. Further, upside-down inverted U-shaped (saddle-shaped) outer suspension bodies 99a, 99a are welded to the outer end portions of the hanging hangers 98, 98, respectively, and the inner end portions of the aircraft body are downwardly U-shaped. The inner suspension bodies 99b and 99b of the mold are welded, and the suspension hooks 99f, 99f, 99f, and 99f that suspend the containing bag 97 on the outer suspension bodies 99a and 99a and the inner suspension bodies 99b and 99b are movable up and down. Attach to.

  Instead of welding the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b, the outer ends of the hanging hangers 98, 98 are bent into an inverted U shape (saddle shape), and the inner ends of the aircraft It is good also as a structure which can be attached to the hanging hooks 99f, 99f, 99f, and 99f movably up and down by bending a U-shape.

The protrusion 101 is attached.

  Further, a hole (not shown) in which a female screw is engraved is formed on the rear side or both front and rear sides of the rotating shaft 93, and an adjustment knob 102 in which a male screw (not shown) to be screwed into the hole is engraved. By inserting and rotating the adjusting knob 102 to change the front-rear distance between the second transport frames 78 and 78 and the hanger arms 95 and 95 sandwiching the friction resistors 94 and 94, the frictional resistance is changed. The configuration is as follows.

  If the adjustment knob 102 is provided at the rear end portion of the rotating shaft 93, the auxiliary operator who is on the auxiliary work seat 91 can easily operate. If the adjusting knob 102 is provided at the front end portion of the rotating shaft 93, the control seat 11 is mounted. This makes it easy for the operator to operate and makes it easy to adjust the frictional resistance of the frictional resistors 94 and 94.

  Further, a slide shaft 103 that is slidable in the front-rear direction is provided below the second transport frame 78 on the transport end side of the sorting transport conveyor 87 and on the rear side of the machine body with respect to the rotating shaft 93. A spring 104 for applying tension pressure in the front direction of the machine body is attached to the shaft. Further, an auxiliary hook 105 is provided at the front end of the machine body on the front side of the spring 104 so as to prevent the slack by hanging the front and rear intermediate parts inside the machine bag 97 that enter the lower part of the sorting and conveying conveyor 87, and the rear side of the slide shaft 103. A slide knob 106 is attached at the end and on the outside of the second frame 78 so that the auxiliary operator grasps it by hand and slides the slide shaft 103 back and forth.

  If the slide shaft 103 is provided from the rear end portion of the machine body of the sorting / conveying conveyor 87 to the same position as the front / rear intermediate portion or slightly to the front side of the machine body when not operated, the position of the auxiliary hook 105 can be easily adjusted. Further, the slide shaft 103 may be provided from the front side to the rear side of the machine body. In this case, an operator who is on the control seat 11 can operate the slide shaft 103.

  Then, as shown in FIG. 6, a hanging band hook 107 that hooks a hanging band 97 i inside the body of the storage bag 97 below the sorting and conveying conveyor 87 and on the upper side in the conveying direction of the sorting and conveying conveyor 87 than the rotating shaft 93. Is attached to the upper part of the hanger frame 96 and the hanging band pin 108 for hooking the hanging band 97o on the outer side of the machine body is arranged facing the upper side of the machine body, whereby the accommodation bag hanging device 85 is configured.

  The suspension bands 97i and 97o on the outside of the machine body are members for hanging the accommodation bag 97 containing carrots on a forklift or hoist. The accommodation bag G is configured by the accommodation bag suspending device 85 and the collection table 115.

Next, operation | movement of the said accommodating part G is demonstrated.
At the start of the carrot harvesting operation, the sorting / conveying conveyor 87 is lowered to the lowest position in order to minimize the falling distance of the carrot from the conveying terminal end of the sorting / conveying conveyor 87 to the containing bag 97. Further, the four corners of the storage bag 97 are hooked on the suspension hooks 99f, 99f, 99f, 99f provided on the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b of the front and rear suspension hangers 98, 98, respectively. The opening has a substantially rectangular shape in plan view.

  Then, the front and rear hanger arms 95 and 95 are rotated upward until they contact the upper limit restricting protrusion 101, and the front and rear hanging hangers 98 and 98 are inclined upward from the body inner end toward the body outer end. To do. As the hanging hangers 98 and 98 are inclined upward toward the outer side of the machine body, the suspended storage bag 97 is also inclined upward from the inner edge of the machine body toward the outer edge of the machine body. Become posture.

  At this time, among the suspended storage bags 97, the inner side of the machine body from which the carrot is discharged from the transfer terminal end side of the sorting and conveying conveyor 87 is slackened so that the vertical length is shortened, and the outer side of the machine body is hardly slackened so Length increases.

In addition, the accommodation bag 97 shall be comprised flexibly with cloth material, a synthetic fiber, etc.
Further, the outer end of the machine body of the discharge shooter 89 is inserted into the inner end of the storage bag 97, and the inner end of the storage bag 97 is inserted under the transfer end side of the sorting and conveying conveyor 87. Auxiliary hook 105 is hooked in a suspension hole (not shown) formed at a substantially central portion in the front-rear direction. Further, the suspension band 97 i on the inner side of the body of the container bag B is hooked on the suspension band hook 107, and the suspension band 97 o on the outer side of the body is hooked on the suspension band pin 108 on the hanger frame 96.

  The hanger arms 95 and 95 are held in an inclined posture set by the operator due to the frictional resistance of the frictional resistors 94 and 94. However, if the hanger arms 95 and 95 are left unattended, the adjustment knob 102 is rotated. Thus, the frictional resistance force of the frictional resistance bodies 94 and 94 disposed between the second transport frames 78 and 78 and the hanger arms 95 and 95 is adjusted. When the adjustment knob 102 is rotated in the tightening direction, the contact area and the contact pressure of the friction resistors 94 and 94 are increased, the friction resistance is increased, and the hanger arms 95 and 95 are prevented from moving freely. In addition, if it rotates in the loosening direction, the contact area and the contact pressure of the frictional resistance bodies 94 and 94 will decrease, and a frictional resistance force will become weak.

  Further, when the harvesting operation proceeds and the amount of carrots stored in the storage bag 97 exceeds a certain amount, the auxiliary operator steps on the ascending pedal 92a and extends the elevating cylinder 88 to extend the conveying terminal portion of the sorting conveying conveyor 87. Raise the side.

  While the sorting and conveying conveyor 87 is moving up, the hanger arms 95 and 95 are lowered because the force that the hanger arms 95 and 95 try to move down exceeds the friction resistance of the friction resistors 94 and 94. The lowering of the hanger arms 95, 95 occurs only while the sorting / conveying conveyor 87 is raised so as to secure a carrot storage space in the storage bag 97.

  When the hanger arms 95 and 95 are rotated downward, the hanging hangers 98 and 98 are rotated with the hanger frame 96 as a fulcrum, the outside of the body of the hanging hanger 98.98 is rotated downward, and the inside of the body is Rotate upward. Since the outer side of the machine body of the storage bag 97 is positioned upward at the stage of installation, there is almost no change in the position, but the inner side of the machine body is pulled upward by the movement of the hanging hangers 98 and 98. Thereby, the slack which had arisen inside the machine body of the accommodation bag 97 is eliminated according to the rising amount.

  It should be noted that there is almost no change in the drop between the transfer terminal portion of the sorting and conveying conveyor 87 and the storage bag 97 due to this operation, and the end portion of the discharge shooter 89 hangs down into the storage bag 97, so that the storage bag It does not protrude from 97.

  Further, every time the harvesting operation proceeds and the amount of carrots stored in the storage bag 97 exceeds a certain amount, the transfer terminal end of the sorting transfer conveyor 87 is raised, the hanger arms 95 and 95 are rotated downward, and the storage bag 97 is also rotated. The inside of the fuselage is pulled upward to secure a space for storing carrots in the storage bag 97, and the carrot piles biased toward the inside of the fuselage are destroyed.

  Then, when the sorting and conveying conveyor 87 is rotated upward and the hanging hangers 98 and 98 are in a substantially horizontal posture, the slack on the inside of the machine body of the storage bag 97 is eliminated, and the vertical heights on the inside and outside of the machine body are substantially the same. Become. In this state, since approximately 200 kg of carrots are stored in the storage bag 97, the operator stops traveling of the machine body and lowers the storage bag 97 outside the machine.

At this time, the hanger arms 95 and 95 are configured to contact the lower limit restricting protrusions 100 and 100.
However, if it takes more time to replace the storage bag 97, such as when all the carrots in the field can be harvested in a few meters, the lid that closes the upper opening of the storage bag 97 is suspended. If it is hooked on the outer suspension bodies 99a and 99a and the vertical height from the outside of the body of the storage bag 97 to the vicinity of the central portion in the left-right direction is increased, it can be accommodated if it is several meters (several kg) of carrots. The labor for replacing the bag 97 is saved, and the work efficiency is improved.

Even in this state, there is almost no change in the drop between the transfer terminal portion of the sorting transfer conveyor 87 and the storage bag 97.
When the storage capacity of the storage bag 97 is full, the machine body, the pulling and transporting device 24, the sorting and transporting conveyor 87, etc. are stopped, and the storage bag 97 is removed from the hanging hooks 99f, 99f, 99f, and 99f, and the slide knob 106 is removed. The auxiliary hook 105 is removed from the storage bag 97 by pulling backward from the machine body. When the hand is released from the slide knob 106 due to the tension of the spring 104, the auxiliary hook 105 automatically returns to the sorting / conveying conveyor 87 and the substantially central portion in the front-rear direction of the storage bag 97 when the auxiliary hook 105 is attached.

  Further, by operating the operation handle to lower the mounting table 112 forward or backward, the storage bag 97 in which carrots are stored slides down the mounting table 112 with its own weight, so when the storage bag 97 is lowered to the front side of the aircraft When the storage bag 97 is moved backward and the storage bag 97 is lowered to the rear side of the vehicle, the storage bag 97 storing about 200 kg of carrots is lowered from the storage part G and installed in the field.

When the harvesting operation is completed, the hanger arms 95 and 95 are again brought into contact with the upper limit restricting protrusion 101, and the sorting and conveying conveyor 87 is rotated upward to the uppermost position.
With the above-described configuration and operation, there is almost no slack on the outer side of the body of the storage bag 97 from the start of the work to the time of replacement, so it is prevented that carrots enter the slack and reduce the storage capacity of the storage bag 97. The replacement frequency of the bag 97 is reduced, the work efficiency is exchanged, and the labor of the operator is reduced.

  With the conventional method of attaching the storage bag, slack is generated on both sides of the aircraft, so ginseng enters the slack, and even if the storage bag is lifted, the slack cannot be removed. The frequency was high.

  In addition, it was possible to eliminate the slack in the storage bag by moving the sorting transport conveyor up and down, and to secure the storage space, but every time the slack was removed, the operator had to operate the sorting transport conveyor, The efficiency was reduced. In particular, in the case of an auxiliary worker who performs sorting, the sorting accuracy during operation has been reduced.

  And since the drop between the transfer terminal end of the sorting conveyor 87 and the left and right sides of the housing bag 97 is almost constant, the carrot can be prevented from being damaged by the impact of the drop, and the product value of the carrot is improved. To do.

  Further, normally, the rotation of the hanger arms 95 and 95 is regulated by the frictional resistors 94 and 94, and the hanger arms 95 and 95 are configured to rotate downward only while the sorting and conveying conveyor 87 is raised. When the sorting and conveying conveyor 87 is operated in accordance with the change in the amount of ginseng stored in the storage bag 97, the inner sides of the hanging hangers 98 and 98 can be moved upward, so the storage amount of the storage bag 97 is automatically set. Since the slack inside the machine body of the storage bag 97 is automatically eliminated, it is not necessary to move the sorting and conveying conveyor 87 up and down to remove the slack, and the work efficiency is greatly improved.

  Further, by providing an upper limit restricting projection 101 that determines the upper inclination posture limit of the hanger arms 95, 95 on the second transport frame 78 on the front side of the machine body, the operator can easily understand the position where the hanger arms 95, 95 are set, The positions of the hanger arms 95, 95 can be determined so that the containing bag 97 is full.

  In addition, since the upper limit restricting protrusion 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit restricting protrusion 101 is within the working range of an auxiliary worker who sorts the carrots being transported by the sorting transport conveyor 87. Since it does not exist, it is possible to prevent the auxiliary worker from colliding or getting caught on clothes, and the burden on the worker is reduced.

  The lower limit regulating members 100 and 100 are also provided on the second transport frame 78 on the rear side of the machine body. However, the lower limit regulating members 100 and 100 are located at the inner end portions of the machine bodies of the hanging hangers 98 and 98, and the normal sorting operation is finished. Since there is no interference with the operation of the auxiliary worker, there is no problem.

  In order to prevent the operator from forgetting to bring the hanger arms 95, 95 into contact with the upper limit restricting protrusion 101, forgetting to set can be prevented by writing a note on the second transport frame 78 on the rear side.

  The outer suspension bodies 99a and 99a are provided upward at the outer end portions of the hanger 98 and 98, and the inner suspension bodies 99b and 99b are provided at the inner end portions of the suspension hangers 98 and 98. Since the lowering hooks 99f and 99f are positioned below the hanging hooks 99f and 99f on the outer side of the machine body, when the storage bag 97 is installed, the difference in height between the outer side and the inner side of the body of the storage bag 97 becomes large. Further, ginseng is more difficult to spill from the outside of the body of the containing bag 97.

  Further, when the left and right end portions of the hanging hanger 98 are bent to form the outer suspended body 99a and the inner suspended body 99b, it is possible to reduce the cost because it can be constituted by a single bar.

  Then, the suspension belt 97i provided on the inner side of the container bag 97 is hooked on the suspension belt hook 107 below the sorting and conveying conveyor 87, and the suspension belt 97o provided on the outer side of the housing body is hooked on the suspension belt pin 108 on the hanger frame 96. Thus, the suspension bag 97i, 97o pulls the storage bag 97, so that slack in the storage bag 97 can be reduced.

  Further, by hooking the auxiliary hook 105 into the hole at the substantially central portion in the front-rear direction of the storage bag 97, the slack generated at the substantially central portion in the front-rear direction inside the body of the storage bag 97 can be reduced. It is hard to get into the slack of the room, and sufficient storage space can be secured.

  When the slide knob 106 is pulled to the rear of the machine body, the slide shaft 103 slides to the rear of the machine body and the auxiliary hook 105 is detached from the storage bag 97, so that the storage bag 97 filled with carrots and the sorting and conveying conveyor 87 are transported. Since the auxiliary hook 105 can be removed without entering the narrow space between the lower end portion and the end portion, the work efficiency is improved and the labor of the operator is reduced.

  Further, when the hanger arms 95 and 95 are brought into contact with the upper limit restricting protrusion 101 and the sorting and conveying conveyor 87 is rotated to the uppermost position, the hanging hangers 98 and 98 are rotated and the outer sides of the hanging hangers 98 and 98 are outside the body. Since the end portion is located inside the end portion of the body frame 1, the hanging hangers 98 and 98 that protrude from the body frame 1 do not collide with a wall or the like, and damage to the body is prevented.

  Further, since the end portion of the discharge chute 89 is hung inside the storage bag 97, there is no space where the carrot between the discharge chute 89 and the storage bag 97 can be dropped. Carrots can be prevented from falling and the product value of the carrots is improved.

  If the width of the discharge shooter 89 in the longitudinal direction of the machine body is substantially the same as the width of the sorting and conveying conveyor 87 in the longitudinal direction of the machine body, the effect of preventing the carrot from falling is further improved.

(Installation discharge unit)
Next, the configuration of the placement discharge unit H will be described.
As shown in FIGS. 2 and 12 to 14, a folding support frame 109 is provided at the rear side of the left and right sides of the body frame 1 through the folding rotation shaft 109 a in the longitudinal direction of the body, and the folding support is supported. The mounting frame 110 is attached to the frame 109 on the rear end side of the frame 109 so as to be rotatable in the left-right direction of the body with the folding rotation shaft 110a as a rotation fulcrum. Further, a rotation support joint 111 is rotatably provided through the folding rotation shaft 109a on the front side of the machine body from the mounting frame 110, and the rotation support joint 111 passes through the folding rotation shaft 109a. A cavity is formed below.

  A bearing 112a having a diameter in close contact with the inner surface of the hollow support joint 111 is provided to be inclined toward the body frame 1, and the discharge rotation shaft 112 is provided on the bearing 112a on the left and right sides of the body. It is attached in an upwardly inclined posture located on the upper side (the side away from the body frame 1). Further, the left and right mountings that hold the left and right sides of the storage bag 97 on the base side (one side of the machine body on the left and right sides) and the end part side (the other side of the machine body on the left and right sides) of the discharge rotation shaft 112 in the upward inclined posture and prevent the fall Side walls 113 and 113 are provided so as to be pivotable in the vertical direction, and the rear portion of the storage bag 97 is hung on the hanging hangers 98 and 98 between the left and right sides of the left and right mounting side walls 113 and 113. A post-mounting wall 114 that holds The mounting rear wall 114 and the left and right mounting side walls 113 and 113 may be welded and connected, or a metal plate may be integrally formed to form a U-shaped mounting wall in plan view.

  Further, a flat plate-shaped receiving plate 115 that receives the bottom portion of the storage bag 97 is provided between the left and right of the mounting side walls 113, 113 and on the front side of the mounting rear wall 114. And the reinforcement bar 116,116,116 which reinforces the receiving plate 115 is each provided in the front-and-rear end part of this receiving plate 115, and the bottom face of the front-back direction substantially center part, and the bottom part of the accommodation bag 97 which accommodates ginseng is supported. At the same time, a mounting bucket 117 is configured to rotate downward with the discharge rotation shaft 112 as a rotation fulcrum and to slide the storage bag 97 down to the field.

  If the left and right width of the receiving plate 115 is longer than the left and right widths of the hanger arms 95 and 95, even if the receiving bag 97 is inflated by carrots stored therein, it fits within the left and right width of the receiving plate 115, and Since it is possible to prevent the storage bag 97 from protruding from the mounting side walls 113, 113, the storage bag 97 protruding from the receiving plate 115 is prevented from coming into contact with the radiator cover 10 a or the like of the control unit B and is prevented from being damaged. In addition, the carrot falls from the damaged part and is damaged, and the commercial value is prevented from deteriorating.

  Further, an operation support plate 118 in a posture inclined upward toward the rear of the machine body is fixed to the left and right other ends of the mounting frame 110 in the above-described manner in a posture perpendicular to the discharge rotation shaft 112, and the discharge rotation shaft The lower end portion of the rotation plate 119 is pivotally attached to the left and right other end portions of the body 112 so that the discharge rotation shaft 112 can be rotated in the longitudinal direction of the body. On the upper side of the rotating plate 119, a long hole 119a is formed in the front-rear direction.

  Then, between the hole 119a formed in the rotating plate 119 and the upper part of the operation support plate 118, a screw groove is cut on the surface of one bar, and a screw groove is formed on the inner surface of the other hollow bar. A mounting / discharging unit is provided by providing a screw rod 120 that is formed by knitting and aligning the screw grooves of each rod, and attaching an operation motor 121 that rotates and expands and contracts the screw rod 120 to the rear end of the screw rod 120. H is configured.

  When the operation member 121a such as a switch or a lever for operating the operation motor 121 is provided on the operation panel 12, it is easy for the operator to operate according to the instruction of the auxiliary operator. It becomes easy for a person to operate while lowering the storage bag 97, and the work efficiency is improved.

Further, the screw rod 120 may be replaced with a telescopic member such as an electric cylinder or a hydraulic cylinder.
The placement bucket 117 is arranged in an upward inclined posture in which the discharge turning shaft 112 serving as a turning fulcrum of the placement bucket 117 is positioned upward on the left and right sides of the body, and the placement bucket 117 is rotated upward as much as possible. In this case, the posture becomes substantially parallel with respect to the farm scene, and when the loading bucket 117 is rotated downward, the front end of the loading bucket 117 is lowered from the body frame 1 to the left and right sides of the body as the lower side. It is set as the structure which leaves | separates.

  With the above configuration, during the harvesting operation, the mounting bucket 117 can be rotated to the left and right sides of the machine body to support the bottom of the storage bag 97, and after the work is completed, the mounting bucket 117 is rotated to the left and right sides of the machine body. Since it can be folded by moving it, the left and right width of the aircraft is compact, the aircraft can be easily placed on transport means such as a light truck, and it can be accommodated in a storage location such as a warehouse without taking up too much space it can.

  Further, since the discharge rotation shaft 112 is folded and disposed below the rotation shaft 109a, the upper end portion of the rotation support joint 111 can be disposed at substantially the same position as the upper end portion of the body frame 1 and the boarding step 90. Therefore, the rotation support joint 111 does not prevent the auxiliary worker from getting on and off the body frame 1 and the boarding step 90, and the work efficiency is improved, and the auxiliary worker hits his / her foot to cause injury or roll. Safety is improved.

  Further, the discharge turning shaft 112 is arranged in an upward inclined posture that is positioned upward on the left and right other sides of the machine body, and when the mounting bucket 117 is turned upward as much as possible, the posture becomes a substantially parallel posture with respect to the field scene. When the loading bucket 117 is rotated downward, the housing bag 97 is separated from the fuselage by being separated from the fuselage frame 1 to the left and right sides of the fuselage as the front end of the loading bucket 117 is lowered. Can be lowered in a direction away from the radiator cover 10a projecting outward from the left and right sides of the control unit B, so that the storage bag 97 lowered on the farm field is prevented from coming into contact with the radiator cover 10a and the like. An operator picks up the carrot without the impact of the bag 97 contacting the radiator cover 10a or the carrot stored by the container bag 97 being broken due to the contact. That it is no longer necessary.

  In particular, when the storage bag 97 is damaged, an alternative storage bag 97, a container or the like must be prepared, and the carrots stored in the damaged storage bag 97 must be transferred. Labor must be expended, and there is a risk that the spare storage bag 97 will be insufficient and the ginseng harvesting work in the field may not be completed. However, this configuration can solve this problem. .

Further, if the ginseng is prevented from falling from the containing bag 97, it can be prevented that the ginseng is damaged by the impact of the drop, so that the commercial value of the ginseng is improved.
Furthermore, since the storage bag 97 lowered to the field is located further to the left and right sides of the machine than the outer end of the mounting bucket 117, the storage bag 97 is placed on the field when returning to the carrot pulling and harvesting operation. Since the distance for separating the airframe can be shortened in order to avoid the storage bag 97, the work efficiency is improved, and it is prevented that the unharvested carrots planted on the adjacent strips are crushed, Ginseng yield and commercial value are improved.

  When the storage bag 97 is lowered toward the front side of the machine body and returned to the pulling and harvesting operation, the machine body is first moved backward to securely separate the storage bag 97 from the mounting bucket 117 and then the machine body is advanced. When the placement bucket 117 located at the end of the left and right sides of the machine body is retracted to a position where it does not come in contact and moves forward and there is no possibility of coming into contact with the storage bag 97, an operation of returning to the carrot harvesting strip is performed.

  Since the interval between the machine body frame 1 and the mounting bucket 117 is increased as the mounting bucket 117 is rotated downward, the storage bag 97 while the operator manually operates the speed change operation lever 13 in the reverse direction. When lowering the machine, it is possible to work with one body to one foot entering this space, so it is difficult for the operator to move away from the reverse machine and the container 97 can be safely lowered onto the field. it can.

  In addition, in the case of the interval enough to put in one body, the operator can operate the machine body without leaving the control unit B until the storage bag 97 gets down to the field, so that the safety is further improved.

  Further, since the storage bag 97 can be discharged in a direction away from the machine body, the storage bag 97 that is lowered to the farm field even when the length of the mounting frame 110 protruding to the left and right sides of the machine body is shortened is the control part B. Since it is configured not to contact the radiator cover 10a and the like, and the center of gravity of the mounting / discharging part H can be brought close to the center part in the left-right direction of the aircraft, the weight balance of the aircraft is stable, and the straightness and maneuverability are improved. The drawing efficiency is improved and the work efficiency is improved.

  In addition, since the left and right widths of the airframe are shortened, the airframe can be configured compactly, so that the airframe can be easily stored, and the mounting / discharging portion H is less likely to come into contact with a bag or a wall during turning. Efficiency is improved.

  The left and right mounting side walls 113, 113 and the mounting rear wall 114 are provided on the left and right sides of the receiving plate 115 and the upper outer edge on the rear side, thereby causing a carrot deviation and a swinging of the airframe in the housing bag 97. Since the storage bag 97 can be prevented from falling from the mounting bucket 117, the carrot is prevented from being damaged by the impact of the drop, and the product value of the carrot is maintained, and the receiving plate 115 is disposed below the storage bag 97. It is possible to prevent the enormous weight of the storage bag 97 that has been reduced by supporting the hanger 98 and 98, the hanger arms 95 and 95, and the like from being damaged, thereby improving durability.

  Further, since the operator operates the operation member 121a to drive the operation motor 121 to expand and contract the screw rod 120 that rotates the mounting bucket 117 up and down, the operator can move the mounting bucket 117. Since it is not necessary to spend a force on the vertical rotation, the work efficiency is improved and the labor of the operator is reduced.

  Further, by providing the operation support plate 118 to which the screw rod 120 is attached at a right angle with respect to the discharge rotation shaft 112, the mounting bucket 117 can be rotated at a constant speed in accordance with the expansion and contraction of the screw rod 120. As a result, the rotating operation of the loading bucket 117 is not wasted, the work efficiency is improved, and the discharge rotating shaft 112 is hardly overloaded, and the durability is improved.

(Containment discharge process)
Next, the process from the storage of the crop accompanying the harvesting to the field discharge after the storage will be described with respect to the sorting conveyance unit F, the storage unit G, and the mounting discharge unit H related to the handling of the storage bag 97 as a storage container.
Specifically, as shown in FIGS. 19 and 20 in order of the side view and the plan view of the main part of the harvesting machine, the sorting and conveying conveyor 87 as the sorting and conveying device, the auxiliary work seat 91 for sorting work, and the container A linkage configuration between the hanging hanger 98 that is a mounting member and a receiving plate 115 that is a collection table that receives the storage container 97 as a placement and discharge device will be described.

And the conveyance end is supported so as to be movable up and down, and a storage bag 97 as a flexible storage container is suspended and supported by the storage container mounting member 98 at the transfer end, and below that The bottom surface of the storage container 97 is received so as to be discharged from the field by a collection stand 115 provided so as to be tilted and grounded. By the tilting and grounding operation, the storage container 97 storing the harvested crop is discharged to the field and then collected by the recovery machine.

  As shown in the rear view of the main part of each device in the crop accommodation process, as shown in FIG. 21, it is a heavy burden after ensuring the adjustment of the discharge drop at the end of conveyance of the sorting and conveying device 87 related to the sorting and accommodation of the crop. In order to avoid the low-level sorting operation, it is configured as follows.

  The sorting and conveying device 87 connects the first conveying frame 77 for laterally feeding received crops in the vehicle width direction and the second conveying frame 78 for sorting work so as to be rotatable via a relay sprocket shaft 80a. The second transport frame 78 is configured to be tiltable with the sprocket shaft 80a as a fulcrum. The second transport frame 78 is provided with a lifting cylinder 88 that is an end raising / lowering operation member that can be controlled to be lifted and lowered in the tilting range from the horizontal transport posture to the full accumulation height of the storage container 97 for adjusting the height. In addition, the switch S and the pedal T are arranged in the vicinity of the auxiliary work seat 91 as a lifting operation tool. Further, a yield sensor U that detects the amount of crops passed by an infrared sensor or the like is provided at the conveyance end of the sorting and conveying device 87.

  The storage container mounting member 98 includes hooks 99f that open and support the opening of the storage container 97 at the four corners, and is supported by a hanger frame 96 attached to the transport terminal portion of the second transport frame 78 of the sorting transport device 87. Thus, the lifting height of the opening of the storage container 97 can be adjusted by tilting the second transport frame 78.

  The collection table 115 includes an elevating seat 202 that can be moved up and down via the telescopic support device 201, and the elevating seat 202 is configured so that the container 97 can be placed on the bottom. The expansion / contraction support device 201 covers an expansion / contraction member 203 such as a pantograph mechanism provided on the collection table 115 with an expansion / contraction protection cover (not shown), and an expansion / contraction cylinder 204 which is an expansion / contraction operation member provided under the collection table 115. It connects with 203, and it is comprised so that expansion-contraction control is possible, as shown in the rear view at the time of the expansion | extension (a) and reduction (b) as shown in FIG.

  The expansion / contraction range of the expansion / contraction support device 201 is set such that the height of the lifting / lowering seat 202 is the upper limit at a position corresponding to the conveyance end of the sorting conveyance device 87 when the second conveyance frame 78 is in the horizontal conveyance posture. And the telescopic operation tool V by a switch or the like is disposed in the vicinity of the auxiliary work seat 91. Further, a lower limit sensor W, which is a lower limit detection member (W) for detecting the lower limit position of the lifting / lowering seat 202, is provided on the telescopic member 203.

  The recovery table 115 is disposed so as to protrude rectangularly from the outer side of the machine body at the conveyance end position of the sorting and conveying device 87, and as shown in FIG. 23, a plan view accompanied by a rear view of the main part is provided along the inner end portion thereof. 211 and a tilting motor 211a which is a tilting movement member, and the discharge operation tool X tilts the outer end portion of the collection table 115 so that it can be grounded, so that the storage container 97 can be discharged outward. The vicinity of the rear end portion of the support shaft 211 is supported by a vertical support shaft 212, and the collection table 115 is rotated rearward so that the discharge direction of the storage container 97 can be adjusted. Further, the vertical support shaft 212 is provided with a return spring 212a, and can be returned to the transport end position of the sorting transport device 87, which is the storage position, by raising the ground contact end.

  The collection table 115 is provided with hooks 215 and 215, and the collection table 115 is restrained by being hooked on the support frame 216 on the airframe side, and the discharge direction can be adjusted by removing the hooks 215 and 215 when the collection table 115 is lowered. Configure. Further, the front and rear edges of the collection table 115 are provided with walls 213 and 214, respectively, and the front edge wall 213 is configured to be higher than the rear edge wall 214, whereby the collection table 115 is accommodated when the storage container 97 is lowered outward. It can be easily removed from 97.

(Accommodation discharge control)
Next, a description will be given of a control system for handling the storage container 97 when storing the crop accompanying harvesting and discharging the field after storage.
As shown in FIG. 24, the control system for handling the storage container 97 has a block configuration diagram as a control condition by the control unit 221, and a lifting operation tool for adjusting the transport terminal height of the sorting transport device 87 up and down. The switch S and the pedal T, the switch V which is an expansion / contraction operation tool for adjusting the support height of the lifting seat 202 of the collection table 115, and the discharge operation for discharging the storage container 97 by tilting the collection table 115 The signals of the tool X, the yield sensor U that detects the amount of crops stored in the storage container 97, and the lower limit sensor W that detects the lower limit support height of the lifting seat 202 are input.

  In addition, as control targets by the control unit 221, a lifting cylinder 88 for adjusting the transport terminal height of the sorting transport device 87 to be raised and lowered, a telescopic cylinder 204 for adjusting the support height of the lifting seat 202 on the collection table 115, The tilting motor 211a, which is a tilting movement member of the recovery table 115, and the lifting operation tools S and T, the telescopic operation tool V, the yield sensor U, and the discharge operation tool X are configured to be controllable.

(Elevator control)
As an example of handling the lifting / lowering seat 202, the yield interlocking control of the lifting / lowering seat 202 that controls the expansion / contraction cylinder 204 to be reduced by the yield sensor U according to the amount of stored crops is configured. When storing the crop, the second transport frame 78 of the sorting and transporting device 87 is set in the horizontal transport posture, the transport end is lowered to the lowest position, and the lifting seat 202 is raised to the highest position and the harvested crop is started to be stored in the storage container 97. To do. From the time when the lifting / lowering seat 202 reaches the lowering limit, the lifting / lowering operation tools S and T are used to adjust the conveying terminal height of the sorting and conveying device 87.

  With the above control, within the range in which the lifting / lowering seat 202 can be lowered, the head from the end of the conveyance to the accumulation height position of the stored crop in the storage container 97 is adjusted while keeping the discharge height of the sorting and transporting device 87 constant. Therefore, the protection of the contained crops can be ensured, and the appropriate sorting work height can be maintained with the sorting and conveying device 87 as the horizontal conveying posture.

That is, the telescopic support device 201 is reduced in accordance with the amount of crops stored in the storage container 97, and the height of the lifting seat 202 that supports the storage container 97 so that the storage container 97 can be raised is adjusted. Since the height of the stored crop in the storage container 97 is automatically adjusted from the end, the crop is prevented from being damaged by the impact of dropping, and the commercial value of the crop is improved.
Further, since the amount of the storage container 97 automatically increases, it is possible to prevent the crop from falling without completely entering the storage container 97, thereby preventing the crop from being damaged and improving the commercial value. There is no need to pick up the harvested crops and the labor of the worker is reduced.
Further, since it is not necessary to change the capacity of the storage container 97 by raising and lowering the transfer terminal end side of the sorting and conveying device 87, the operator sorts the crops moving on the sorting and conveying device 87 having the same work height. Therefore, working in an unreasonable posture is prevented, the labor of the operator is reduced, and the sorting accuracy is improved.

Further, in addition to the yield interlocking control, the control unit 221 is configured to stop the detection of the yield sensor U by the detection of the lower limit sensor W. With this control configuration, when the lifting / lowering seat 202 reaches a predetermined lower limit position, the telescopic operation member 204 stably holds the lifting / lowering seat 202 at the lowered position, and the operator raises the transport terminal side of the sorting and transporting device 87. Thus, it is possible to shift to an operation process for increasing the storage amount of the storage container 97.
Furthermore, by operating a notifying means such as a buzzer by detection of the lower limit sensor W, it is possible to smoothly shift to the height adjustment of the sorting and conveying device 87 by the lifting operation tools S and T.

(Elevating seat adjustment)
Next, as an example of handling the telescopic operation tool V, the control unit 221 is configured to limit the operation of the telescopic cylinder 204 by the operation of the telescopic operation tool V to the case where the lower limit sensor W is not detected in the yield interlocking control. . By this intervention-limited control, only in the process in which the lifting / lowering seat 202 is lowered to the lower limit position, the extension / contraction support device 201 is extended / contracted by the extension / contraction operation member 204 by the intervention operation by the extension / contraction operation tool V, and the height of the lifting / lowering seat 202 is adjusted. The

  Therefore, by adjusting the drop of the input of the crop stored in the storage container 97 to the height position, the crop can be prevented from being damaged by the impact of the drop, and the commercial value of the crop can be improved. In addition, when the lifting / lowering seat 202 is lowered to the lower limit position, the lower limit sensor W detects and thereafter the operation of the telescopic operation tool is not accepted, and thus the influence of the erroneous operation of the telescopic operation tool when the lifting / lowering seat 202 is at the lower limit position. Since the situation where the crop overflows from the storage container 97 due to the decrease in the capacity of the storage container 97 accompanying the upward movement of the lifting / lowering seat 202 is prevented, the product value is improved and the fallen crop is picked up. There is no need to collect, and the labor of the operator is reduced.

(Sorting conveyance adjustment)
Next, as an example of handling the lifting operation tool by the switch S and the pedal T, in the yield interlocking control, the operation of the lifting cylinder 88 by the operation of the lifting operation tools S and T is limited to the case where the lower limit sensor W detects. The control unit 221 is configured. This intervention-limited control can prevent the lifting / lowering of the sorting / conveying device 87 due to an erroneous operation while the lifting / lowering seat 202 is lowered to a predetermined position by the lowering control in conjunction with the yield sensor U. A sudden increase in the emission head due to the rise of the department side is prevented, and the crop is damaged by the impact of the fall and the commercial value is prevented from being lowered.

(Containment process adjustment)
Next, as an example of an extended handling of the lifting operation tool by the switch S and the pedal T, when the lower limit sensor W is not detected in the yield interlocking control, the telescopic cylinder 204 is set according to the operation of the lifting operation tools S and T. When controlling the operation and stopping the function of the yield sensor U and detecting the lower limit sensor W, the control unit 221 is configured to control the operation of the elevating cylinder 88 by operating the elevating operation tools S and T.

  With this control configuration, when the lifting operation tools S and T are operated while the lifting / lowering seat 202 is lowered to the predetermined lower limit position, the height adjustment is performed by stopping the automatic operation of the telescopic support device 201 by stopping the yield sensor U. Therefore, it becomes possible to adjust the drop between the sorting and conveying device 87 and the storage container 97 to a height at which the crop is hardly damaged, the quality of the crop is maintained, and the lifting operation tools S and T are released. Since the automatic operation of the telescopic support device 201 is restored, the work efficiency is improved. On the other hand, after the lifting / lowering seat 202 reaches the lower limit position, the head can be adjusted by moving the lifting / lowering operation pedal T or the lifting / lowering operation switch S to raise and lower the conveyance end of the sorting and conveying device 87. As described above, the configuration is such that the expansion / contraction operation member 204 or the terminal lifting / lowering operation member 88 is operated by the common operation tool depending on whether the lower limit sensor W is in the detection state or the non-detection state, thereby reducing the number of operation tools. The aircraft configuration is simplified.

(Discharge control)
Next, for the handling example of the collection table 115, the control unit 221 is configured so that the tilting operation of the tilting motion member 211a by the operation of the discharge operation tool X is limited to the case where the lower limit sensor W detects. With this operation-limited control, when the storage container 97 is lowered to the field, the collection table can be tilted and grounded only when the lifting / lowering seat 202 is lowered to the lower limit position on the collection table, so that the storage container 97 moves to the field. Since the head drop is kept small, the stored crops are prevented from being damaged, and the commercial value is improved. Moreover, since the weight of the storage container 97 can be received by both the lifting / lowering seat 202 and the recovery table, the load applied to the tilting support mechanism is reduced and the durability is improved.

(Stem and leaf alignment device)
Next, in the case where the drawing / conveying device 24 is double digging, as shown in FIG. 25, a plan view (a) and a side view (b) of the main part thereof, the foliage aligning device 231 below the drawing / conveying device 24. And forming a gap Q for changing leaves in the corresponding section, it is possible to cut a plurality of carrots P to be pulled up in a lump and align them in a row.

  Specifically, as shown in FIG. 26, the foliage alignment device 231 has left and right belts 232 and 232 arranged opposite to each other with a predetermined gap R therebetween, and a lump mechanism of carrots is provided by a post-drive driving clamping mechanism. Configure to temporarily hold. The pulley shafts 233 and 233 at the front and rear of the foliage aligning device 231 are connected to the upper pulling / conveying device 24 through a universal joint to receive power, and further, two carrots are aligned in a row at the inlet. Therefore, the left and right guides 234 and 234 are arranged so as to spread forward, and the rotating bodies 234a are arranged so that the carrot can be protected and guided.

(Another embodiment)
Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIG. 15 and FIG. 16, the folding rotation shaft 109 a in the longitudinal direction of the machine body constituting the mounting bucket 117 and the folding support frame 109 and the machine frame 1 are arranged in the longitudinal direction with respect to the folding support frame 109. A long rotating frame 122 is provided, and a vertical space portion in which the rotating frame 122 and the folding support frame 109 can enter is formed between the body frame 1 and the left crawler 6L.

  A rotation support shaft 123 that is a rotation fulcrum when the rotation frame 122 rotates in the left-right direction is provided at a substantially intermediate position in the front-rear direction of the rotation frame 122, and the rotation support shaft 123 is disposed in the space. Place in the department. Further, the front end portion of the rotating frame 122 is disposed on the left and right sides of the body of the control unit B from the radiator cover 10 a and on the side of the control seat 11, and an operator can turn the rotating frame 122 to the front end portion of the rotating frame 122. An operation handle 124 for rotating the 122 in the left-right direction is attached. Further, the rear end portion of the rotation frame 122 is connected to the mounting frame 110, and a rotation cylinder 125 that extends and contracts in the left-right direction of the body is provided in the boarding step 90. The rotation frame 122 is provided at one end of the rotation cylinder 125. Are connected.

  The rotating cylinder 125 expands and contracts when the operator manually operates the operation handle 124. When the operation handle 124 is not operated, the rotation cylinder 125 is a gas cylinder that restricts the rotation operation of the rotation frame 122, or is attached to the operation handle 124. A switch or a button is attached, and an electric cylinder or a hydraulic cylinder that rotates the rotating frame 122 by extending and contracting by operating the switch or button is used.

  As a result, it is possible to switch between a configuration in which the fuselage frame 1 and the loading bucket 117 are in a parallel posture and a configuration in which the front end of the loading bucket 117, that is, the discharge port of the containing bag 97 is separated from the fuselage in the left and right directions of the fuselage. A simple mounting / discharging unit I is configured.

  With the above configuration, when the storage bag 97 is lowered from the placement bucket 117, the operation handle 124 is operated to extend the cylinder 125, and the rotation frame 122 is rotated in the left and right directions of the machine body. Since the position at which 97 is lowered to the field can be set to a position far away from the machine body, the storage bag 97 is further prevented from coming into contact with the machine body, and the carrot falls due to the impact of the contact or damage of the storage bag 97 due to contact. In addition, the labor value of the carrot is reduced by improving the product value of the carrot and omitting the work of picking up the carrot that has fallen.

  In addition, since the distance between the storage bag 97 lowered to the farm field and the machine body is greatly increased, the distance traveled by the track separating the machine body from the storage bag 97 in order to avoid the storage bag 97 lowered to the farm field is further shortened. As a result, the work efficiency is improved, and it is prevented that the unharvested ginseng planted on the adjacent strips is crushed, so that the yield and product value of the carrots are improved.

  Then, by providing the pivot support shaft 123 serving as the pivot point of the pivot frame 122 between the upper and lower sides of the fuselage frame 1 and the crawler 6L, the fuselage frame 1 and the mounting bucket 117 are in a parallel posture. Since the center of gravity of the loading and unloading part I can be brought closer to the center part in the left and right direction of the aircraft, the balance of the body is stabilized, the straightness and maneuverability are improved, the accuracy of carrot extraction is improved, and the work efficiency is improved. improves.

  Moreover, since the left and right widths of the airframe are shortened, the airframe can be configured compactly, so that the airframe can be easily stored and the loading / discharging portion I is less likely to come into contact with a bag or a wall during turning. Efficiency is improved.

  Furthermore, by arranging the operation handle 124 on the front end side of the rotating frame 122 and on the side of the control seat 11, the operator can operate the rotating frame 122 without getting off the control seat 11. The labor of the worker is reduced.

  In addition, by switching the rotation operation and the stop state of the rotation frame 122 with the cylinder 125, the operator can rotate the rotation frame 122 with a light force, thereby reducing the labor of the operator. Since the rotating frame 122 can be prevented from rotating freely even if the aircraft tilts in the left-right direction, the balance of the aircraft does not change abruptly, and the straightness and extraction accuracy of the aircraft are stabilized.

  Alternatively, as shown in FIGS. 17 and 18, the folding support frame 109 is slidably disposed in the horizontal direction between the upper and lower sides of the aircraft frame 1 and the left crawler 6 </ b> L, and on the aircraft frame 1 in the horizontal direction of the aircraft. The fixed side (cylinder case side) of the slide cylinder 127 that expands and contracts is disposed, and the extendable side of the slide cylinder 127 is connected to the folding support frame 109. Then, an extended control panel 128 is provided on the left and right sides of the control panel 12 of the control unit B, and a slide switch 129 for extending and retracting the slide cylinder 127 on the extended control panel 128 and a mounting bucket 117 are rotated up and down. A rotation switch 130 for operating the operation motor 121 is attached, and the folding support frame 109 is inserted between the upper and lower sides of the body frame 1 and the crawler 6L, and the folding support frame 109 is from the left and right other side ends of the body frame 1. Also, a mounting discharge portion J that can be switched to a form located outside is configured.

  Further, the extension control panel 128 is provided with a reset switch 131 for placing the placing bucket 117 in a horizontal posture and moving the folding support frame 109 between the machine frame 1 and the crawler 6L, and the folding support frame 109 on the machine frame 1. You may provide the setup switch 132 which moves the mounting bucket 117 downward while moving outside the body left-right other end part.

  When the reset switch 131 is operated when the mounting bucket 117 is in a horizontal posture, the operation motor 121 is not operated and only the slide cylinder 127 is contracted and the mounting bucket 117 is folded. Even if the body frame 1 is rotated along the moving shaft 109a, the folding support frame 109 is slid by contracting the slide cylinder 127.

  On the other hand, when the setup switch 132 is operated when the slide cylinder 127 is in the extended state, the operation motor 121 is operated to lower the placement bucket 117.

  With the above configuration, when the harvested carrots are stored in the storage bag 97, the slide cylinder 127 is contracted so that the folding support frame 109 is inserted between the upper and lower sides of the body frame 1 and the crawler 6L, and the center of gravity position of the mounting bucket 117 is set. Since it can be close to the center in the left-right direction of the fuselage, the weight balance of the fuselage is stabilized, the straightness and maneuverability are improved, the accuracy of carrot extraction is improved, and the work efficiency is improved.

  In addition, since the carrot discharged from the sorting and transporting conveyor 87 falls to the front and rear of the storage bag 97 and the substantially central position in the left-right direction, the carrots stored in the storage bag 97 can be stacked in a mountain shape. The transport end of the conveyor 87 can be moved up and down, or the slide cylinder 127 can be expanded and contracted to move the loading bucket 117 in the left-right direction to evenly collapse the carrot stack. Is housed.

  When the storage bag 97 is lowered, the slide cylinder 127 is extended, the machine body and the placement bucket 117 are separated from each other, and then the placement bucket 117 is lowered, so that the position where the storage bag 97 is lowered to the field is greatly separated from the machine body. Therefore, the storage bag 97 is further prevented from coming into contact with the fuselage, the carrot is not dropped due to the impact of the contact or the damage of the storage bag 97 due to the contact, and the product value of the carrot is improved. The labor of the worker is reduced by omitting the work of picking up the carrots.

  In addition, since the distance between the storage bag 97 lowered to the farm field and the machine body is greatly increased, the distance traveled by the track separating the machine body from the storage bag 97 in order to avoid the storage bag 97 lowered to the farm field is further shortened. As a result, the work efficiency is improved, and it is prevented that the unharvested ginseng planted on the adjacent strips is crushed, so that the yield and product value of the carrots are improved.

  Furthermore, by switching the sliding movement of the folding support frame 109 in the left-right direction by expanding and contracting the slide cylinder 127, the operator can slide the folding support frame 109 with a light force, thereby reducing the labor of the operator. In addition, since the folding support frame 109 can be prevented from sliding freely even if the aircraft tilts in the left-right direction, the balance of the aircraft does not change abruptly, and the straightness and the extraction accuracy of the aircraft are stabilized.

  Then, by attaching an extension control panel 128 provided with a slide switch 129 and a rotation switch 130 for operating the slide cylinder 127 and the operation motor 121 to the control panel 12, the operator can place the loading / discharging unit while operating the aircraft. Since the operation of J can be performed, work efficiency is improved.

  In addition, since the reset switch 131 and the setup switch 132 that integrate the operations of the slide switch 129 and the rotation switch 130 are provided, the work procedure is simplified, and the work efficiency is further improved.

  The configurations of the placement discharge section I shown in FIGS. 15 and 16 and the placement discharge section J shown in FIGS. 17 and 18 can be added to the placement discharge section H of this embodiment.
